This miniature board book literally bounces! Each Little Bouncer book in this series comes with an illustrated pair of hind legs printed on a heavy cardboard attachment that extends from the book's bottom surface, directly beneath the animal who's pictured on the front cover. The pair of legs is attached to the book with an internal spring. Kids can stand the book on its feet, then press down and let go — and the entire book hops into the air! When kids open these books they'll find comical pictures on every board page and brief, slightly silly stories about animals who love to hop, jump, and bounce.
